They (Gnome-devs) should made it easier to create/edit themes.The documentation/wiki should also show improvements/more examples.

I'd also searched for a good tutorial, but mostly they also give instructions on howto modified existing theme's.But it should be better to create/write from scratch, as the same way you write a HTML-page.

I agree, but the problem with writing from scratch is that most themes are pretty much identical code wise (apart from the theming of the individual widgets) since they both need to contain roughly the same code in order to work. So there's no point starting from scratch because you'll probably end up with code that's very similar to another theme, even if the actual look and feel of your theme is different.

But apart from that, there should be an easier way to edit themes, if only to encourage more people to create them.

Absolute perfection. Stylish and easy on the eyes (both literally and figuratively). I spent my first points on DeviantArt on this theme and I couldn't have spent them any better. Keep up the great work, please!

Extract the archive that you download, and move the folder in the archive to a folder called .themes in your home folder. If ti doesn't exist, just make it. Also, you have to press Control+H to get it to show.

Wow, thank you! I'm not sure if future releases of Iris will support Trusty, since the version of Gtk it uses is getting old now, but I still appreciate your work and I'm sure it will be useful for many people.

Thanks for this great looking theme.Can I make a few suggestions?1) Same dark bgcolor for Synaptic Package Manager, LibreOffice and GTK2 apps like my favorite text editor KKEdit2) Dark bgcolor for Chrome browser so that same monochrome (light) icons look also nice and visible there3) Same or some other dark bgcolor for sidebar (e.g. Nautilus) or providing such an option maybe4) Other color variants, e.g. Blue (for the highlights, selected text, etc.)

Thanks for the suggestions, and I'm glad you liked the theme 1) I think that having some apps with a dark background and others with a lighter one would be inconsistent. Theming specific Gtk apps is fairly hard anyway, and near impossible (for me at least) for Gtk 2 applications.2) Dark theming on Chrome seems to break the visual theming, as it's new rendering engine doesn't fully implement gtk theming.3) That's a nice idea, I'll take it into consideration 4) I've had requests for blue variants already - it's extremely simple to do, just changing a few files, but I'm not sure if it would be reasonable for Iris, where I intended the theme to be heavily based around the bolder accent colour (which can be seen with how subtly it is used).

If you are using elementary OS Luna, then, unfortunately, Iris does not support it as it uses outdated software. In the upcoming release of elementary OS (Freya, still in development), Wingpanel changes opacity automatically depending on the wallpaper you use.
